It's a toss up between #Gaming and #Offtopic. I'd tend to lean more towards #Offtopic because it certainly fills in the "distinct culture" category as well as having more recognized users. The problem with it the past few years, in my opinion, is it's become a cesspool of roleplaying, terrible shitposts, bait, etc. It's not really a shadow of what it once was but somehow maintains a unique identity even if it is somewhat... annoying.
